T all whom it may concern:

Be it known that I, CHARLES IV, MORGAN, a citizen of the United States,and a resident of the city of Chicago, in the county of Cook and Stateof Illinois, have invented a new and useful Vise, of which the followingis a full, clear, and exact description.

My invention relates to improvements in vises or holding appliances usedin bench 0 testing of small machines such as automobile magnetos,generators, or starters, and the object of my improvement is to simplifymanufacture by altering the structure of my original form of visedescribed in a preceding specification Serial Number 590,983.

I11 the original form, I provided my rise with three adjustable clampingmembers, two of which are located on one side of a machine to be securedin the vise and the third of which is located on the other side.-

I retain these salient features in this new vise which I choose to termthe improved form.

In the drawings forming a part of this specification, like characters ofreference indicate corresponding parts in all views. Fig. 1., shows theimproved form of my vise completely assembled; Fig. 2., a cross-sectionlengthwise through the carriage; Fig. so 3.. the fork-hook member; Fig.l, plan views of the front pressure screw U-block in two positions.

I will now describe my vise shown in Fig. 1., and Fig. 2., 18 is thecarriage of the vise supported on V-shaped guide rails 19, 19 both ofwhich are to be secured to a work bench. These rails 19, 19 gripd'ovetails 20, 20 and in the center of one of the rails 19., I mount aset screw This per- '3 inits locking the carriage at any desired point.In carriage 18, there are a plurality of transverse slots 23, 23, 23, Inone of these there engages a fork-hook member 22. The U-block 24; withits push-screw 25 is designed to be placed at any desired position onthe f0I'l -l100l This U-block 24 has the extensions 26, 26 Fig. 4., soas to permit quick adjustment of screw 25 by setting 2d crosswise insome cases which has the effect of advancing the screw 25 a distance Dwithout turning 25 that amount. The distance D is approximately thewidth of a slot 29, 29 are rear L-shaped members pro Divided and thisapplication filed Serial No. 678,534.

vided with shoulders 28, 28. These L- members 29, 29 Fig. 1., and Fig.2., engage with a transverse slot 27.

Having described the essential parts composing my improved form of vise,I will now describe its use. The magneto, generator or starter to besecured in the vise is placed on carriage 18, Fig. 1., in properalignment with the pulley of the motor that is to drive it and theL-members 29, 29 are adjusted to suit its particular dimensions. Thenthe fork-hook 22 is hooked into the slot giving the best adjustment. Nowthe U-block 2 1 is slid up to the desired position, set in one of thetwo positions it may have on the fork 22 and the screw 25 is given a fewturns to complete the tightening operation.

Now by comparing the construction of my improved form of vice shown inthis specification with that of my original form shown in a precedingone, it will be obvious to one versed in the art of manufacture thatthis improved form is much easier to construct. The original formrequired the drilling of a number of holes with considerable accuracy aswell as some tapping operations while this improved form of vicerequires the drilling of only a few holes and these with no particularaccuracy, and also a lesser number of tapping operations.

Having described my invention,

I claim z 1. In a vise or holding appliance for bench testing ofautomobile magnetos, generators or starters, the combination comprisinga supporting carriage to receive the work, the top of said carriagehaving multiple parallel slots extending su stantially from one edge tothe opposite; parallel guides or rails to support the carriage; a benchor table to which the guides are rigidly attached; a set-screw in one ofthe rails to secure the carriage rigidly to the rails at any desiredpoint; tWo members of si1nilar pattern, comprising in combination therear jaw of the vise, each L-shaped and shouldered and mounted in one ofthe slots in the carriage; a fork-hook member engaged with another slot,the hook of the said fork-hook gripping the edge of the slot; a-U-shaped block with pressure screw mounted in its center, the dimensionsof the l O O block being sufficient to permit the arms of the U toembrace both tines of the fork on the fork-hook member.

2. In a Vise indicated in Fig. 1., the carriage 18 to receive the work,the said carriage provided with. multiple parallel slots 23, 23, 23 and27; the parallel guides or rails 19, '19 rigidly attached to a bench 01:table top; the said bench or table top with the attached rails 19, 19 toform a support for the carriage 18; the members 29, 29 engaging slot 27and in combination forming the rear aw of the vise; the member 22, thehook of said member in engagement with one of the slots 23 and the forleof said member projecting vertically from the top of the carriage, thesaid member 22 being one component of the front aw of the Vise; theU-block 24: with the pressure screw 25 mounted at its center, the saidU-block 24 together with its pressure screw 25 being the secondcomponent of the front jaw of the vise; all substantially as shown forthe purpose specified.
